hyphenate-character CSS property

The hyphenate-character CSS property sets the character (or string) used at the end of a line before a hyphenation break.

Both automatic and soft hyphens are displayed according to the specified hyphenate-character value.

Try it

hyphenate-character: auto;
hyphenate-character: "=";
hyphenate-character: "—";
<section id="default-example">
  <p id="example-element">An extra­ordinarily long English word!</p>
</section>
#example-element {
  border: 2px dashed #999999;
  font-size: 1.5rem;
  text-align: left;
  width: 7rem;
  hyphens: auto;
}

Syntax

css
hyphenate-character: <string>;
hyphenate-character: auto;

The value either sets the string to use instead of a hyphen, or indicates that the user agent should select an appropriate string based on the current typographic conventions (default).

Values

<string>

The <string> to use at the end of the line before a hyphenation break. The user agent may truncate this value if too many characters are used.

auto

The user-agent selects an appropriate string based on the content language's typographic conventions. This is the default property value, and only needs to be explicitly set in order to override a different inherited value.

Examples

This example shows two identical blocks of text that have hyphens set to ensure that they break wherever needed, and on soft hyphen breaks (created using &shy;). The first block has the value of the hyphen changed to the equals symbol (=). The second block has no hyphenate-character set, which is equivalent to hyphenate-character: auto for user agents that support this property.
